ask Your support, they know ...

but remember there is not such a thing as a maintenance level for any IBM products

the general flow is...
IBM ships a product with some maintenamce applied,

with the product usually a tape is shipped cotaining up to the last month od released PTFs for the product

from then on ( depending on the agreement with IBM ) a monthly PTF tape might be shipped

so generally speaking a produst might be to a PUT ( Ptf Update Tape )
od a certain month

but, there are some other concerns ...
PTFS are atomic

some PTFs might not have been applied due to HOLD status or missing prerequisites

some other ptfs might have been applied on specific needs ( single request to IBM )


but... why do You want to know ??

it' s a long time that IBM ( and other products too ) are installed using SMPE
but if You clobber the system without using SMPE icon_eek.gif

learn about zOS installation and maintenance

http://www.redbooks.ibm.com/abstracts/sg246982.html?Open

again, as I said before,
there is not such a thing as a system maintenance level

as per IBM PTF philosophy You will only find a module maitenance level
wander thru the SMPE interactive dialogs

once upon a time it was a habit to apply periodically preventive maintenance,
it meant to have available most of the time a sistem for a thorough regression test,

now it is more common to ...
install a product with all the preventive maintenance applied up to the installation date
run all the tests fo the new environment
apply maintenance for errors discovered during the test
deploy the whole shebang to production

after that apply maintenance with a strict screening methodology

HYPER mods released by IBM
FIXES for malfunctions found during normal operations...

testing is easier, ( just try to reproduce the error by rerunning the failng program )
usually only a few modules are involved...
fallback will not be painful
